Question

Michael has collected seashells every year that his family has gone to the beach. In his collection, he has 75 shells. Of those shells, 1/3 have a hole in them. Help Michael write an equation to represent the number of shells in his collection with holes. After that, determine how many shells Michael collected that have a hole in them.

Answer 1

1/3*75=25

Explanation:

Draw a rectangle draw 2 lines within the rectangle to show 3 boxes. Shade in 1 part of that (that represents 1/3).

Consider that 1/3 is equal to x/3

So

X/3×75

75(x/3)

25x

Transform the value of x to 1

So answer is

25

Answer 2

For the first part: 75 ÷3

For the second part: 25 shells

Explanation:

So in the first part, you're looking to find 1/3 of the 75 shells. If you were to divide those shells into 3 groups, you need to find how many shells are in each group. You can do that simply by dividing 75 ÷3.

In the second part, you just solve the equation 75 ÷3. That gives you the answer of 25.
